I am still unclear on what the usage of this flag. I mean what variable
from fit_image_setup_verify() and fit_config_verify_required_sigs()
to be feed to this function as a flag. Maybe a void pointer is better
for different platform to pass context data and cost to specific data
structure. For example, pass data of image that to be verified.
fit_board_skip_sig_verification(const void *data)

Will check this file for more modification and test.

Thank you!
